Due to the significant role in understanding cellular processes, the decomposition of Protein-Protein Interaction (PPI) networks into essential building blocks, or complexes, has received much attention for functional bioinformatics research in recent years. One of the well-known bi-clustering descriptors for identifying communities and complexes in complex networks, such as PPI networks, is modularity function. The contribution of this paper is to introduce heuristic optimization models that can collaborate with the modularity function to improve its detection ability. The definitions of the formulated heuristics are based on nodes and different levels of their neighbor properties. The modularity function and the formulated heuristics are then injected into the mechanism of a single objective Evolutionary Algorithm (EA) tailored specifically to tackle the problem, and thus, to identify possible complexes from PPI networks. In the experiments, different overlapping scores are used to evaluate the detection accuracy in both complex and protein levels. According to the evaluation metrics, the results reveal that the introduced heuristics have the ability to harness the accuracy of the existing modularity while identifying protein complexes in the tested PPI networks.
This research aims to investigate the extent to which the Iraqi audience relies on interactive television programs as a source of information regarding national issues and their resulting impacts. It seeks to identify the types and nature of attitudes developed among the public towards national issues through these programs and determine the prominent topics and issues highlighted to the audience. The researcher employed a field survey as the primary research method, employing a questionnaire for data collection along with scientific observation and the Likert three-point scale to measure attitudes. The study was guided by the media dependency theory. A sample of 520 questionnaires was distributed to residents in

Backgrond: One of the major causes of impaired movements post-stroke is the abnormal phasing of paralytic muscles. Many studies suggested that inappropriate muscle phasing may be associated with enhanced transmission in the monosynaptic Group Ia afferent pathway in the affected limb of post-stroke patients and Group Ia reflexes are abnormally elevated and fail to decrease in amplitude during locomotion.
Objectives: This study was conducted to identify the changes in the Soleus muscle H-reflex excitability at rest in the affected lower limb of post-stroke patients as compared to the contra lateral side and of normal controls.
Patients and methods: The excitability of the m

In different countries of the Muslim world today their presence exists and is active but is confused with mystery and secrecy. The most important characteristic of their political ideology is their dependence on the esoteric exegesis, which they have made an intellectual basis for which their most ideas relate, when they make for everything visible and exposed a hidden matter, not only aware of the esoteric exegesis, which only God knows and entrenched in science, and they mean imams or whoever They are called "(esoteric)" as a result of the Ismaili belief in esoteric interpretation and that everything is apparent inward, as well as they called the ((seven

Show MoreThe present study dealt with taxonomic characters of species Zygophyllum fabago L. in Iraq . this study included the exo-morphological characters which indicated that the species was sub-shrub with solid stem and swallow nodes ,with compound bifoliate and stipulate leaves, the flower is complete and perfect with clawed petals . stamen colored with scaly appendage , fruit capsule with ribs . Anatomical study of vegetative parts indicate that the sclerenchymal tissue was very diffuse in stem such as fibers and sclerides ( stone cells ) , the leaves were bifacial . The geographical distiribution of the species plants was studied . The results supported with photographs
Channel estimation and synchronization are considered the most challenging issues in Orthogonal Frequency Division Multiplexing (OFDM) system. OFDM is highly affected by synchronization errors that cause reduction in subcarriers orthogonality, leading to significant performance degradation. The synchronization errors cause two issues: Symbol Time Offset (STO), which produces inter symbol interference (ISI) and Carrier Frequency Offset (CFO), which results in inter carrier interference (ICI). The aim of the research is to simulate Comb type pilot based channel estimation for OFDM system showing the effect of pilot numbers on the channel estimation performance and propose a modified estimation method for STO with less numb

Patients and methods :A prospective study carried out on 35 patients who underwent adenoidectomy or Adeno-tonsillectomy between May 2004 and October 2005.The patient ages ranged from 3 to 12 years. Five patients were unavailable for follow-up and did not complete the study so they are excluded from. The pre-operative symptoms were Rhinorrohea, Nasal congestion, Headache, Postnasal drainage, Cough, Halitosis and Irritability.
Also recorded was Mouth breathing, Fever and Frequent antibiotic use. Telephone interviews with the patient's caregivers were conducted to collect information followi
Background: Changes of coagulation profile have been described in patients with B-Thalassemia major. Prolongation of prothrombin time and partial thromboplastin time and reduced levels of coagulation factors and natural anticoagulants have been variously described though the mechanisms involved in the thrombotic tendency seen in some Thalassemia patients have not been fully clarified.
Objectives: To investigate changes in the coagulation profile in patients with B-Thalassemia according to the available hemostatic parameters in Thalassemia patients in Al-Karama Teaching Hospital in Wasit governorate.
Methods: Hemostatic variables were studied in pre-transfusion blood samples from 50 transfusion-dependent children with Beta Thalassem
